# 
# Given an array of positive integers `arr`,  find a pattern of length `m` that
# is repeated `k` or more times.
# 
# A **pattern** is a subarray (consecutive sub-sequence) that consists of one or
# more values, repeated multiple times **consecutively** without overlapping. A
# pattern is defined by its length and the number of repetitions.
# 
# Return `true`  _if there exists a pattern of length_  `m`  _that is repeated_
# `k`  _or more times, otherwise return_  `false`.
# 
# 
# 
# **Example 1:**
# 
#     
#     
#     Input: arr = [1,2,4,4,4,4], m = 1, k = 3
#     Output: true
#     Explanation: The pattern **(4)** of length 1 is repeated 4 consecutive times. Notice that pattern can be repeated k or more times but not less.
#     
# 
# **Example 2:**
# 
#     
#     
#     Input: arr = [1,2,1,2,1,1,1,3], m = 2, k = 2
#     Output: true
#     Explanation: The pattern **(1,2)** of length 2 is repeated 2 consecutive times. Another valid pattern **(2,1) is** also repeated 2 times.
#     
# 
# **Example 3:**
# 
#     
#     
#     Input: arr = [1,2,1,2,1,3], m = 2, k = 3
#     Output: false
#     Explanation: The pattern (1,2) is of length 2 but is repeated only 2 times. There is no pattern of length 2 that is repeated 3 or more times.
#     
# 
# **Example 4:**
# 
#     
#     
#     Input: arr = [1,2,3,1,2], m = 2, k = 2
#     Output: false
#     Explanation: Notice that the pattern (1,2) exists twice but not consecutively, so it doesn't count.
#     
# 
# **Example 5:**
# 
#     
#     
#     Input: arr = [2,2,2,2], m = 2, k = 3
#     Output: false
#     Explanation: The only pattern of length 2 is (2,2) however it's repeated only twice. Notice that we do not count overlapping repetitions.
#     
# 
# 
# 
# **Constraints:**
# 
#   * `2 <= arr.length <= 100`
#   * `1 <= arr[i] <= 100`
#   * `1 <= m <= 100`
#   * `2 <= k <= 100`
